Checks your blood for antibodies to West Nile virus, a mosquito-borne infection. Suited to people who think they may have been exposed while travelling.
1 biomarker as listed by Better2Know.
This test looks for antibodies to West Nile virus, a mosquito-borne infection that mainly affects birds but can occasionally infect people, including from an infected pregnant person to a foetus or during breastfeeding, or rarely via infected blood or organs. Most people who catch it have no symptoms, so an antibody test is the main way to find out whether you have been exposed. It measures the one marker, so it will not tell you about any other infection.
There is no comparison group of directly equivalent tests in our data for this listing, so we cannot benchmark it against named competitors. Set against the wider group of immunity tests we track, its £395 price is well above the typical cost for a test of this size, which is the main factor behind its low value for money score.
The listing scores well for clarity, since it sets out the marker tested, the sample type and the turnaround clearly. It scores poorly on collection convenience, because it requires a venous blood draw at a clinic, although a home nurse visit is offered, and on results and follow-up, since results are not reviewed by a doctor as standard.
This suits someone who has been bitten by mosquitoes in an area where West Nile virus circulates and wants to check whether they have been exposed, particularly if they are pregnant or trying to conceive. Because it only measures one marker and carries a high price relative to other immunity tests we track, it is not a general-purpose health check.
There is no equivalent test in our data to compare it against on price or depth, so if you are looking for broader reassurance about recent travel-related infections, it is worth checking whether other providers offer a wider mosquito-borne illness panel.
You have a venous blood sample taken at a Better2Know clinic, or arrange a home nurse visit, and the sample is sent to a local laboratory for processing. Results are ready within 10 days and are sent by email or SMS, with progress tracked through your online Patient Area. The listing does not describe results as reviewed by a doctor as standard.
West Nile Virus Test looks for antibodies to the infection from a single blood sample, priced at £395. That is well above the median for similarly sized immunity tests we track, and there is no comparison group of Better2Know peers in our data for this listing. Results take around 10 days and require a venous blood draw at a clinic or via a home nurse visit.
The listing publishes a detailed description, the full biomarker list, a stated turnaround, clear collection options, the sample type; it does not state what the report looks like.
